CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 542,117, dated July 2, 1895. Application filed December 17,1894. Serial No. 532,095 (No model.)

To afZZ whom it may concern.-

Be it known that l, AUGUSTUS F. STREET, of Zanesville, in the county of Muskingum and State of Ohio, have invented a new and useful Improvement in Oai'Oouplings, of which the following is a specification.

My invention is an improvement in carcouplings and particularly in that class. of such devices having a hinged or pivoted knuckle and devices by which the same is secured in locked or coupled position;v and the invention consists in certain novel constructions and combinations of parts as will bev hereinafter described, and pointed out in the claims. v

In the drawings, Figure lis a top'plan view of my improved coupling. plan view thereof, the bottom plate being removed. Fig. 3 is a cross-section on about vline 3 3 ofFigs. 1 and 2. Fig. 4 is vertical longitudinal section, and Figs. 5 and 6 are detail views. Y

The draw-head A has the mortise B, in one wall of which is formed the seat O for the lock presently described. The hook or knuckle D is pivotedor hinged at E and is provided with a shoulder F, againstwhich the latch G abuts in securing the hook in coupled position. This latch is in the nature of a block and slides back and forth in the mortise B, being actuated forward by a spring H, which ts at its front end in a socket in the rear end of the block and at its rear end upon a pin or stem z', projecting from a base or block I, such block and stem constituting a removable bearing for such spring, so the latter can be conveniently removed and replaced. The latch-block G has a bearingJ for engagement by the cam 7c of the operating-shaft K, and also has a longitudinal slot or groove 7o and atransverse groove k2, which latter forms a way for the lock-bolt L, by which the latch is held in retracted position. This boltL drops by gravity in the seat-socket O in the draw-head when the latch-block is pushed back, and such lock holdsvthe latch in such retracted position until the lock is released, which latter result is accomplished by devices connected with and operated by the knuckle. To this end the lock-bolt has a stud-or projection Z, which enters a groove m in the main section of a drag or slide M,

Fig. 2 is a bottom which .is connected with and moves back and forth with the movement of the knuckle, having to such end a link or pitman section M', connecting the main section of the drag or slide with the knuckle and playing in one direction in the groove la ot' the latch-block and in the other direction in a groove k3 in the draw-head. The groove fm in which the stud Z operates has at its rear end a cam or incline m', which engages said stud Zwhen the drag or slide reaches its foremost position and lifts the bolt out of the socket in the draw-head.

Now in operation if two draw-heads meet, one or both being in uncoupled position, the

yimpact wil-l cause the hooks to couple automatically, and to uncouple it is only necessary to turn the operating-shaft to force the latch back, when thehook or knuckle will be released. N ow, if desired, as, for instance, to set the coupling devices so the cars will uncouple when pulled apart, the latch-block may be pushed back slightly beyond uncoupled position, when its lock will engage in the seat of the draw-head and the latch will be held retracted until the hook or knuckle is drawn forward, in which case the drag or slide will, by engagement with the lock, release the same, and the spring will force the latch-block forward and the parts will be again in position for automatic coupling.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is

l. ln a car coupling the combination with the draw-head, a hinged hook or knuckle, and a latch device for securing such knuckle in coupled position, of a drag or slide connected to and movable back and forth with the said knuckle, the locking device and co-operating mechanism between the slide and locking device substantially as set forth.

2. In a car coupling of the herein described class, a hinged knuckle or hook having an attached drag or slide carried back and forth by the movements of said knuckle, alatch device engaging directly with the knuckle or hook whereby to secure the same in coupled position and elo-operating lock devices between the drag or slide and the latch device all substantially as and for the purposes set forth.

3. In a car coupling the combination of the ICO draw-head the hinged hook or knuckle, the latch by which said knuckle is secured in coupled position a lock by which such latch may be held retracted and releasing devices operating through the movement of the knuckle by which to release such lock all substantially as set forth.

4. In a car coupling the combination of the draw-head, the hinged hook or knuckle the latch bar a lock by which said latch bar is held retracted and the drag or slide movable with the knuckle and adapted to actuate said lock all substantially as set forth.

5. In a car coupling the combination of the draw-head, the hinged hook or knuckle and the drag or slide composed of a main section and a pitnian connecting the same with the knuckle substantially as set forth.

6. In a car coupling the combination of the draw'head, the hook or knuckle, the latch bar by which said knuckle is secured in locked position, the lock carried by such latch and by which it is held in retracted position, and the drag or slide connected with the knuckle and having a portion by which to operateV such lock substantially as set forth.

7. In a car coupling the combination of the coupling devices a slidinglatch having a lock device and a drag or slide movable alongside said latch and having a cam or portion by which to actuate said lock device substaning a mortise and provided in the Walls thereof with a bolt seat and with a groove for the play of the drag pitman, the latch block also having a groove for the play of said pitman, the lock carried by said block and movable into and out ofthe seatin the draw-head and the drag slide having a main section adapted to operate the latch lock and a pit- 5o yman connecting said main section with the knuckle all substantially as and for the purposes set forth.

10. The combination in a car coupling of the latch having a transverse passage or way, `the lock comprising a bolt sliding in such Way and provided with a stud or projection and the slide movable along said latch and having a guidevvay` for said lock stud and a 1 cam to engage said stud substantially as and 6 a for the purposes set forth.

11. The improved car coupling herein described composed of the draw-head having a longitudinal mortise and provided in' the wall thereof with a socket forming a seat for the lock bolt the hook or knuckle, the sliding latch block having a transversely operating lock bolt movable into and out of the seat socket of the draw-head, the spring for actuating said latch block and the drag or slide 7a connected with the hook orknuckle and provided With means by which to actuate the lock bolt substantially as set forth.

l2. In a car coupling the combination of the drawhead the hook or knuckle, the latch 75 block, the spring for actuating said block and n a removable bearing for said spring com-f posed of a block or base and a projecting stern substantially as and for the purposes set forth.
